Hi,I own a Tokina 11-16 f2.8,hmm...I would say wide angle is nice and give you a totally new view through the lens. You should try any UWA lenses out,but please mind the poison 

but quite hard to find. i think someone is selling at alphanatics...

got 1 more question i hear alot ppl say is attach F42 and F58 flash to a55 the they will slow for 1 or 2 sec only flash fire

erm indoor shooting i guess. like weddings in hotels/halls. 
saw those wedding pics where the photog focus sharp2 at the brides finger (pointing to camera) and blur2 background.

8tvt: well, wide open usually use for low light. on apsc, 24mm is almost human eye's range, so oso can b half or full body portrait lens ad. but beware of distortions at the corners, it may ruin ur portrait haha... using for portrait u wan bokeh then can use bigger aperture. it's very flexible actually, tat's y i use it more than my kit lens n i even sold of my kit lens. XP

don get wat u mean here. XP in weddings, better u bring wide lens lo, coz crowded and limited space ma.

zoom it more like this

8tvt: Well done, though it could use just a bit more depth of field.

8tvt, smaller aperture means bigger F.number...
I think if animate object, maybe can use F5.6 and adjust the shutter speed to control the lighting (exposure).

thank you, i like 8 the most though

Huh? Panorama? Usually it's to show a skyline of a place or to show a large expense of landscape. I normally just put the horizon on the lower one third of the frame and then shoot. Determine the start point and end point and just shoot away lor... I have no special rules.

Set to f8 or f11. Focus to infinity or somewhere in the middle of the frame. I usually do horizontal panning lor. Vertical panning I think you should just focus on one subject. Either tower or tree or mountain.

If you have too many conflicting lines maybe you should consider if panorama is the best way to shoot it.
